The Wine
Opportunities to add value
Using the new features and APIs to increase the value of your and our products

6. The Rice Binary incompatible release Function signature changes
RibbonBar
Installer change

7. The Rice – Binary incompatible release
ObjectARX requires Visual Studio 2008 SP1
Rebuild using new ObjectARX
‘17’ branded libs now ‘18’
New .NET assembly versions
Much easier than AutoCAD 2007

8. The Rice – Function signature changes
Custom objects/entities
‘Search and Replace’ changes
InputPointMonitor
New function definition
Old definition deprecated
Other minor changes
See Migration Guide
Minor changes in .NET too

9. The Rice – Custom Object changes
Name changes to overridden functions
Before: public virtual foo(…)
After: protected virtual subFoo(…)
Necessary for new Overrule API

10. The Rice – CUI API and UI Update
Reflects UI changes to RibbonBar/Menu Browser
Significant runtime RibbonBar API changes
AdRibbon.dll

11. The Rice – Installer change
Increment major version number
R17.2 -> R18.0

12. Demo Basic steps to port your ObjectARX application
VS2008 migration wizard
Custom object name changes
Reference new Lib files

20. The Wine – Freeform modeling
AutoCAD 3D isn’t just boxes
New SubDMesh entity
Uses Catmull-Clark algorithm
Edge and surface creasing
Conversion between ASM solid and SubDMesh and back
Available in ObjectARX and .NET

21. What is SubD?
A subdivision surface is a smooth surface created from a coarse mesh.
The smooth surface is calculated by iteratively subdividing each polygonal face into smaller faces that better approximate the smooth surface.

22. Demo – Freeform Modeling
Basic SubDMesh operations
Create from primitive
Create from ASM solid
Apply creases
Transform mesh elements
Convert to ASM solid

23. The Wine – Overrule Protocol
